FRANK HESS, OF DAVENPORT, IOWA, ASSIGNOR T DAVENPORT ICE SHIPPING MACHINE COMPANY, OF DAVENPORT, IOWA, A CORPORATION OF IOWA.

GEARING.

' To all whom it may concern:

Be it known that I, FRANK Hnss, a citizen of the United States, and a resident of Davenport, in the county of Scott, in the State of Iowa, have invented certain new and useful Improvements in Gearing for Operating Ice-Chipping Machines, of which the following is a full, clear, and exact description.

My invention relates to ice chipping inachines, and particularly to that class of machines designed to chip or shave the ice into a finely divided state. The disintegration of ice in this manner has been done before, but the difliculties that have been experienced arose from the irregularity of the pieces of ice and the trouble in handling the same; from the inability of the operator to shave pieces of ice when the same had been reduced to a very small size, and also from the presence of water due to the melting of the ice shavings, before the latter had been deposited in a suitable receptacle.

The object of my invention is to overcome these difliculties, and in addition, to prevent injury to the machine, through carelessness or otherwise, by automatically releasing the carrier employed to move the feeding device to the shaving disk, from the actuating mechanism, when said feeding-device has reached the limit of its advance movement, and also to enable the work of shaving ice to be done quickly and economically. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings :Figure 1 is a side elevation of my invention. Fig. 9. is a plan View thereof. Fig. 3 is a rear end elevation. F i 4 is a plan view of the carrier for utilizmg the motive power of the machine during the advance movement of the feeding device, broken away from the rest of the machine and drawn to a slightly larger scale. Fig. 5 is a vertical transverse sec tion taken on dotted line 99 of Fig. 4; looking in the direction indicated by the arrows. Fig. 6 is a side view of the same looking at it from the rear of the machine and showing the clamping members of the carrier closed and engaging the threaded driveshaft. Fig. 7 is a similar view of said clamp- Specification of Letters Patent.

ing members separated and disengaged from said threaded drive-shaft.

In the drawings A represents suitable standard, which is provided at a suitable point above its base with an arm A, the end of which has a vertical apertured boss in which the vertical post B of a tray 13, can be vertically adjusted by means of a set screw 6. A short distance above the tray B, standard A is provided with a forwardly projecting lug a, to which a drip-pail C is secured, preferably, by means of a lip a. Detailed description of the attaching device of said pail is unnecessary, as any means may be employed for this purpose.

The upper end of standard A terminates in a suitable supporting-frame K, that has an arm 0 projecting to one side, whose extremity is upturned and provided with bearings m, for a drive-shaft 1), whose adjacent end extends through said bearings and is provided with a suitable crank D with which to turn it. The opposite end of driveshaft D extends concentrically through plate (Z, that is preferably cast in one piece with the end of the post of the supporting-frame opposite arm 0, transverse to the axis of the drive-shaft, and said opposite end is journaled in suitable bearings in the central boss 0 of a circular case E, whose marginal edges are flanged circumferentially and secured by means of screws or otherwise to plate (Z. This case E is slightly pan-shaped, but quite shallow, and provides a chamber within which the cutting-disk F revolves. A drainpipe f leads from a suitable opening in its lowermost segment, and conveys the drippings from the chamber of the cutting disk into the drip-pail C, substantially as shown In order to permit the ice to be fed to the cutting-disk, plate (Z is provided with a suitable opening 7' which is located at the rear of the drive-shaft and extends in a vertical direction, preferably, an equal distance both above and below the horizontal plane of the same. The edge of this opening nearest drive-shaft D is vertical, and the edge farthest from said drive shaft is concentric therewith. A trough H, which is preferably cast in one piece with plate (Z and with the upper edge of the supporting-frame, ex-

tends from opening toward the crank end of drive-shaft D. The longitudinal wall of this trough nearest the drive-shaft terminates, preferably, in a plane'slightly below the axis of the drive-shaft, but the opposite wall thereof arises to very near the upper end of opening j and has lugs projecting rearwardly therefrom to which the knuckles of a hinged lid J, covering over the top of the trough, are pivotally connected. This lid J corresponds in transverse section to the upper portion of said opening j, and when it closes down upon the trough, forms four sides of the receptacle, in which the pieces of ice are deposited that are fed to the cutting-disk. Said lid is provided with a finger-grasp 2', with which to raise or lower it, and with a spring snap 70 consisting of a fiat piece of metal, the lower horizontal end of which is secured to the lid, and the upright portion of which has an opening therein which snaps over a suitable protuberance projecting rearwardly from plate (Z, when said lid is closed. By pulling back on the upper end of snap 70, it can be disengaged from this protuberance, and said lid easily raised.

The end of the trough opposite plate cl is open, and is, at the commencement of the operation of the machine, closed by a trans verse feed-plate I, which is of such dimen sions and contours that it fits within the closed trough. The feed-plate I is suitably secured to or cast in one piece with the rear end of a bracket 2, which latter projects horizontally to the rear from a. boss 3, the bore of which is of such diameter that the drive-shaft can freely pass therethrough. This boss is connected with a longitudinally disposed sleeve 4 by means of a web 5, and said sleeve is mounted on a smooth longitudinal and stationary shaft 6. This shaft 6 is in the same horizontal plane as and is parallel with the drive-shaft, and has one end secured in a lug 7 projecting forward from the bearings m on the uppertend of arm 0 of the supporting-frame, and has its opposite end secured in plate d. The end of boss 3 adjacent to said last mentioned bearings is provided with a vertical plate, which extends an equal distance both above and below the drive-shaft, the vertical surface of this plate. facing bearings m, is provided both above and below the drive-shaft, with headed'studs 8, 8, and the barrel of these studs extend through vertical slots 9, 9, in the vertical flange 10, of each of the semi circular clamping-jaws 12, 12. The clamping jaws, when brought together, form a hollow cylinder, and their concave surfaces form a bore that corresponds in diameter to the drive-shaft D, and is provided .with screw-threads that engage the screw-threads of said drive-shaft, extending from its bearing in arm 0 of the supporting-frame,

vertical spindle 16, and the latter 15 to the D lower end thereof, and this spindle is journaled in a vertically disposed bearing in the web 5 connecting boss 3 and sleeve 4. The under surface of the peripheral edge of the upper cam 14 is beveled, andthe upper surface of the corresponding edge of the lower cam is likewise beveled, and when these cams are rotated in the proper direction, they engage the beveled edges 13 of the flanges of the clamps, and simultaneously move said clamps toward each other and into engagement with the threaded drive-shaft, and when said cams are rotated in the opposite direction said clamps are automatically spread apart, out of engagement with shaft B, by virtue of the expansion of the coiledsprings 26, interposed between the butt ends of said clamps on each side of the driveshaft, substantially as shown. The vertical movement of these clamps 12, 12, is guided, as they approach and recede from each other, by the guide-pins 17, 17, one end of each of which is permanently secured in one of said clamps and the other end. portion of each of which is made to reciprocate longitudinally in alining openings in the other clamp.

The lower portion of the boss of the upper cam 14 is provided with an arm 18 that projects toward the front of the machine, and this arm is provided with a handle on its end, and is held in said forwardly projecting position (against the tendency of the same to move into the position shown in dotted lines in Fig. 8, by reason of the expansive properties of springs 26) by an overhanging finger 19 that drops down over the arm 18, substantially as shown in Figs. 2, 3, and 4. This finger is secured to the outer end of a suitably curved arm 20 projecting from a boss 21, ournaled on a stud 22, that projects forward from the side of sleeve 4, and this boss has a downwardly projecting arm 23, whose lower end is curved toward plate cl, which latter, at a point in longitudinal alinement with the end of said arm 23, has a gage-screw 24, tapped into it and locked in any position desired within the limits of its adjustability by a locknut 25.

The operation of my machine is as follows :-After said plate I is moved to the limit of its movement away from plate (I, the lid of the trough is opened and ice placed in the trough and the lid closed again. Handle 18 is then pushed toward plate (Z as far as it will go, and the cams 14 and 15 made to engage the beveled edges of the flanges of the clamps, and cause the latter to simultaneously move toward and engage the threaded drive-shaft D. When said handle has been moved as far as it can go, the finger 19 drops down over the arm of the same, and retains it in its forwardly projecting position, and thereby keeps the clamps in engagement with the drive-shaft. Handle D is then grasped and the drive-shaft turned in the proper direction, whereupon the boss of the carrier mechanism moves forward toward plate (l and carries the feed-plate with it. The small space intervening between the overhanging edge of the lid J and the vertical wall of the trough permitting bracket 2 to move forward with the said boss 3. hen the said plate has moved toward the cuttingdisk as far as it is considered advisable for it to go, the end of the arm 23 will engage the head of the gage-bolt 24:, and the continued revolution of the drive-shaft will cause said arm 23 to move on its pivot and lift finger 19 from in front of the arm of the handle 8, and thereby permit the expansive power of springs 26, 26, to assert itself and force the clamps 12, 12, apart, out of engagement with the threadeddriveshaft. \Vhen this is done the operator grasps the carrying mechanism with his hand, and draws it back as far as it will move on the drive-shaft and stationary shaft 6, and then makes the clamps engage the threaded drive-shaft again and repeats the ope 'ation ml Zz'bz'tam.
